Labour norms & productivity factors
How man-hour norms per device and a site productivity factor turn quantities into a defensible labour cost.
Quantities become labour cost through man-hour norms, crew size, and a site productivity factor — here's the build-up that turns a device count into hours and dirhams.
Start with the man-hour norm
Each device carries a norm — the hours a competent installer needs to fix, terminate, and test it under standard conditions.
Multiply by quantity
The take-off quantity times the norm gives the raw man-hours for each line — before any site reality is applied.
Apply the productivity factor
A high-rise with limited hoist access and night works never installs at book rate — a site factor stretches the hours to what will actually happen.
Cost the crew
Adjusted hours divided across the crew, priced at the all-in labour rate — the labour figure that feeds each unit rate alongside material and plant.
It's in the works.
